Serial No. 388,394.

To all 'whom fit may concern:

Beit known that I, ALBERT L. SESSIONS, a citizen of the United States, residing at Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Corner Irons, of which the following is a Specification.

My invention relates to improvements in corner irons for trunks, boxes and the like, and the objects of my improvement are economy in construction and efficiency in the article, and particularly to make of sheet metal the style of corner irons that have heretofore been made of cast malleable metal.

In the accompanying drawing Figure 1 is a plan view of my corner iron in one form. Fig. 2 is a corner elevation of the same, showing the inner faces. Fig. 3 is a plan view of my corner iron in another form. Fig. 4 is a corner elevation of the same, showing the inner face. Fig. 5 is a plan view of my corner iron in another form. Fig. 6 is a corner elevation of the same, showing the outer faces. Fig. 7 is a sectional view of the same on the line x r of Fig. 5. Fig. 8 is a plan View of my corner iron in another form; Fig. 9 is a sectional view of the same on the line y y of Fig. 8.

In each of the constructions shown, the corner iron is formed of a body portion consisting of a Sheet of metal bent at or near its middle portion to form two leaves at right angles to each other, and a corner reinforcing iece applied to the corner portion of the body, and provided at its end or ends with such additional leaves or flanges as may be desired, according to the style of corner iron to be produced.

The leaves A and B which form the body portion of my corner iron, are cut from sheet metal by suitable dies and unches into a strip of the desired shape which strip is then bent near the middle of its length to make the said leaves stand at an angle to each other and form at their junction a right angular corner extending in a right line across the said body portion from edge to edge thereof. I also prefer to strike u the transverse ribs or bends 10 at Suitab e distances fromthe corner, to form shoulders for the edges of the corner reinforcing piece C when the said piece is applied on the outer surface of the body as in Figs. 1 and 2. This rib or bend 10 leaves the inner face of each leaf mainly in one lane, substantially the same as if the rib or end was omitted. The corner piece C consists of two main leaves 11 and 12 standing at right angles to each other and of suitable dimensions to have their edges abut against the shoulders formed by the ribs 10, as shown in Fig. 1.

The lower end of the corner piece C, that is the part adjacent to the lower edge of the body portion, is provided with a bottom leaf or flange 13 in the form of a quadrant, the metal at the junction of the leaves 11 and 12 with the leaf 13, extending around the lower edge of the body leaves. The leaf B of the body portion is designed to rest upon a cleat on the side of the trunk or box instead of resting directly on the said side. The corner reinforcing piece is therefore provided at its upper end with the leaf or flange 14, to rest upon the upper edge of the said cleat. The metal at the junction of the leaves 14 and 12 extends over the top edge of the leaf B of the body portion. The two parts, the body portion and corner reinforcing piece thus formed, are secured directly together in any proper manner, as for example by means of rivets 15 whereby the body and reinforce are connected as one piece independently of the means for securing the iron to a trunk or box. The corner iron shown in Figs. 1 and 2 is designed to be placed on the lower right hand corner of a trunk or the upper left hand corner of a cleated box, and it is evident that these irons can be made in rights and lefts without changing the construction. Corner irons formed in one piece of metal with the two main leaves and the minor leaves or flanges herein described, are older than my invention.

By my improvement I am enabled to construct these corner irons from sheet metal, and hence at less cost. At the same time I provide a corner reinforce Where the iron is of a double thickness and the article is thereby very strong and efficient.

If desired, instead of placing the corner reinforce on the outer side of the body portion, it may be placed on the inner side thereof, as shown in Figs. 3 and 4. The body portion consists of the leaves A1 and B1 and instead of the rib 10 of Figs. 1 and 2, these are provided with an oset 1()a to form an inner shoulder for the edges of the corner reinforcing piece Cl to abut, and so as to bring the inner faces of the projecting portion of the leaves A1 and B1 in the plane of the inner faces of the leaves 11a and 12a of the corner piece. The corner piece is provided at its upper and lower ends with the flanges or leaves 13a and 14a, which correspond with the flanges or leaves 13 and 14 of Figs. 1 and 2. The same general construction of an inside corner reinforce is shown in Figs. 5, 6 and 7, with additional features whereby the two parts will stay together without the employment of the rivets 15, shown in the preceding figures. The leaves A2 and B2 are notched or recessed on each edge from the corner to the offsets 1()a as shown at 21, Figs. 6 and 7, and they corner reinforcing piece C2 is swaged up to form shouldersor projections 16 on the outer faces of the leaves 11b and 12D that fit into the notches 21 and hold the two parts together. This corner piece has the leaves or flanges 13b and 14b corresponding to the like leaves or flanges in the preceding views.

The construction shown in Figs. 8 and 9 is in general the same as in Figs. 1 and 2, but has in additionthereto a rounded and outwardly projecting lower corner 17 at the junction of its main leaves 11C and 12c and the leaf or flange 13c at the lower end of the corner piece C3 is extended in the` form of a strap leafinstead of a quadrant. The leaf or flange 14 at the upper end is the same as in Figs. 1 and 2. The swell or rounded corner 17 of the leaves A3 and B3 can be swaged or struck up in dies at the same time that the said leaves are bent into their right angular osition and stock enough may be left at tlie ower edge of the metal to form the bridge 18 at the junction of the said leaves. The corner reinforce is also provided with an angular corner and a corner swell 19 that fits over the outside of the corner swell or projection 17 of the body portion, and with an oset 20 t0 form an inner shoulder for the edge of the gridge 18 to abut against, as best shown in I claim as my invention 1.
